However, there exists an interesting sub-category of pulsars with flat PA swings, low \(\dot{E}\)  and relatively high linear polarization fraction. Some of these pulsars have profiles with very large widths such as PSRs J1232–4742 (Figure REF ) and J1842+1332; presumably these are nearly aligned rotators where the line of sight remains within the beam. This is reminiscent of the profiles of radio-loud magnetars such as XTE J1810–197 [1]} and PSR J1622–4950 [2]}. Others such as PSRs J0108–1431 and J1511–5414 (both shown in Figure REF ) have narrow profiles, either because the line-of-sight just grazes the beam edge or because the emission is from an isolated patch far from the magnetic axis on the leading or trailing edges.
